Answer:
d. 76(cos(3π/16) +i·sin(3π/16))
Step-by-step explanation:
To form the product of 38cis(π/8) and 2cis(π/16), multiply the magnitudes and add the angles:
38cis(π/8) × 2cis(π/16) = (38×2)cis(π/8 +π/16) = 76cis(3π/16)
___
In this context, a·cis(b) ≡ a(cos(b) +i·sin(b))
Given:
20 ounces of water
someone finishes 55% of water
What is left?
20 × 0.55 (55% =

= 0.55)
11
20 - 11 = 9
There are 9 ounces of water left
